BACKGROUND OF THE INVENTION
The present invention relates to a glass substrate transport box in which glass substrates are sequentially guided and stored in a box body from a lateral direction by a transport device.
[0002]
[Prior art]
Conventionally, various types of substrates such as a glass substrate for a base glass liquid crystal display, a glass substrate for plasma display, a hybrid IC ceramic substrate, a wafer, or a finished panel manufactured using these substrates (hereinafter simply referred to as “glass substrate”), for example. A box as shown in FIG. 7 has been known as a transport box used when transferring from a glass manufacturer to a device manufacturer.
In FIG. 7, 01 is a glass substrate carrying box, which is composed of a bottomed main body portion 02 having an open upper end and a lid body (not shown), and the main body portion 02 has both sides or lower sides of a plurality of glass substrates 03. A pair of insertion plates 04 having a plurality of longitudinal grooves 04a for supporting (not shown) are inserted. These glass substrates 03 are engaged and supported one by one in the longitudinal grooves 04a of the opposing insertion plate 04, and are transported by covering the main body unit 02 with the lid from above to hold the upper side of the glass substrate 03. However, in recent years, the vertical and horizontal dimensions of glass substrates have been increasing due to increased transport efficiency of glass substrates, improved loading efficiency, and reduced unit price per number of transported sheets. Dimensions of 1800 × 2000 × 0.7 are becoming mainstream.
When trying to insert a glass substrate of the above dimensions into a glass substrate box from above with a conventional size, there is a problem that the end of the glass substrate hits the ceiling and cannot be inserted from above.
The present invention has been made paying attention to such problems, and provides a glass substrate transport box that can be easily stored without hitting the ceiling even in the case of a large-sized glass substrate that has recently become mainstream. With the goal.

If formed in this way, one step of the lid opening / closing step can be omitted. Moreover, each cover body 12 and 15 can also be integrated with a hinge.
[0023]
Next, a method for housing the glass substrate in the glass substrate transport box will be described in detail.
[0024]
As shown in FIG. 4A, the glass substrate 1 is adsorbed by a vacuum suction tool 3 attached to a transporting machine (hereinafter referred to as a transporting device) 2 such as a special forklift or a crane, for example, in the box body 4. It is conveyed from the horizontal direction.
[0025]
The box body 4 is composed of a ceiling plate 5, a bottom plate 6, a vertical side plate 7 and a pair of horizontal side plates 8a and 8b shown in FIG. 1, and a ceiling surface pad 9 and an inner surface of the ceiling plate 5 and the bottom plate 6 are provided. Since the bottom surface pad 10 is adhered, and the ceiling surface pad 9 and the bottom surface pad 10 are provided with a plurality of parallel grooves Y and Y ′ so as to be aligned with each other, the glass substrate 1 has the parallel groove The glass substrate 1 is guided into Y and Y ′, and when the glass substrate 1 is held in the vertical state and further moved rightward from the position of FIG. 4B to the position of FIG. Since the pad 11 is provided with a plurality of vertical grooves G so as to be aligned with the parallel grooves Y and Y ′, the upper and lower ends of the glass substrate 1 are held in a state perpendicular to the parallel grooves Y and Y ′. The tip of the glass substrate 1 is guided into the vertical groove G. At the same time, the vacuum suction tool 3 of the transfer device 2 releases the suction of the glass substrate 1, and the single glass substrate 1 is positioned in a state where it is securely held from the three directions of the parallel grooves Y, Y ′ and the vertical groove G. Then, the storing process of one glass substrate 1 is completed.
[0026]
By sequentially repeating this process, a predetermined number of glass substrates 1 are accurately positioned and stored in the box body 4 as shown in FIG.
[0027]
At the same time as the glass substrate 1 is stored, the side of the glass substrate 1 is closed by the side lid pad 13 provided on the inner surface of the side lid 12 for closing the opening K as shown in FIG. When the edge S is pressed in the direction of the arrow, as shown in FIG. 5 (c), the side lid pad 13 is kept in a state where the side edge S of the glass substrate 1 is always pressed in a compressed state. The
[0028]
In order to hold and fix this state, for example, the box main body 4 and the side cover 12 are connected by the connecting metal 14 provided on the box main body 4 shown in FIGS. The glass substrate 1 is locked and securely held and fixed.
[0029]
As another example, as shown in FIGS. 6A, 6 </ b> B, 6 </ b> C, and 6 </ b> D, a notch opening K ′ can be formed in a part of the ceiling plate 5. Also in this case, the glass substrate 1 is transported from the lateral direction by the transport device 2 as shown in FIG. 6A in the same manner as in the first embodiment shown in FIGS. As shown in FIG. 6 (b), when a predetermined number of glass substrates 1 are stored, in addition to the side lid pad 13 of the side lid 12, the glass is applied by the ceiling lid pad 16 formed on the ceiling lid 15. If the substrate 1 is pressed from the direction of the arrow as shown in FIG. 6C, the glass substrate is not only pressed from the lateral direction by the side lid pad 13 but also from the upward direction by the ceiling lid pad 16. Since 1 can be pressed, the glass substrate 1 is stored in a state of being securely fixed in the box body 4 as shown in FIG. The glass substrate transport box accommodated by the above method is used as a box that is transferred from a glass manufacturer to a device manufacturer, for example.
